G9184 Global Mixed-mode Technology 500mA Low Dropout Linear Regulator Features General Description The G9184 is a high performance positive voltage regulator designed for use in applications requiring very low Input voltage and low dropout voltage. It operates with a VIN as low as 1.5V with output voltage 1.2V. The supply current is 80µA. The G9184 features low dropout, ideal for applications where VOUT is very close to VIN. The over-current protection limit is set at 550mA typical. An overtemperature protection circuit is built-in in the G9184 to prevent thermal overload. Additionally, the G9184 has an enable pin to further reduce power dissipation while shutdown. In the shutdown mode, the maximum supply current is less than 1µA. The G9184 provides excellent regulation over variations in line, load and temperature. Input Voltage as Low as 1. 5V 240mV Dropout @ 300mA, as VO is 1.5V ±2% Output Voltage Output range from 0.8V to 1.8V (50mV increments) Over Current and Over Temperature Protection Max. Supply Current is Shutdown Mode <1µA Small Ceramic Output Capacitors Enable Pin SOT-89, SOT-223 , SOT-23-5 and ADFN1.5X1.5-6 Packages Applications VID Power Supplies PDAs Notebook Computers Cell Phones The G9184 is available in the power SOT-89, SOT-223, SOT-23-5 and ADFN1.5X1.5-6 package. It is available from 0.8V to 1.8V, 0.05V increments, internally preset outputs. Ordering Information ORDER NUMBER MARKING OUTPUT VOLTAGE TEMP.
